An combined form of the devices 'his' and 'her' with the similar usage in referring to a subject (or possessive, attributive) of both, either, or neither gender.

'Hir' and related nominative 'shi' are seen most often in internet-presented stories involving (the usually pornographically inclined presence of) hermaphrodites or those capable of changing their sex with ease.

A pronoun used when the gender of the subject is unknown, neutral, undefined, or male and female simultaneously, or alternating between the two without breaking the flow of the sentence. Replaces 'Their', 'His/Her', 'His or her'

A fake pronoun used mainly by perverts on the internet (usually lesbians, and gay men who want to change gender) to show themselves to be a hermaphrodite in either roleplay scenarios, stories, and may even convince themselves that they are one in real-life.
